CD4052B: Use CD74HC4052M instead of CD4052B

Part Number: CD4052B
Other Parts Discussed in Thread: SN74LV4052A, CD74HC4052

Hello,

My current design use CD4052B with 3.3V VDD and I suffering from huge resistance above 10Khz switching frequency on A and B pins,

I saw many suggestions from E2E forum to use CD74HC4052M instead of CD4052B when using 3.3V.

Did CD74HC4052M will be less resistance in 3.3V VDD ?


Did CD74HC4052M  is a fully replacement to CD4052B ? (footprint, functionality)

Thanks.

    Yes; both the CD74HC4052 and SN74LV4052A can replace the CD4052B, and are better at low voltages.

    Which is better for new design ? (longevity)

    As far as I can see, both are sold in comparable numbers.

    They have somewhat different electrical characteristics (the CD has higher bandwidth, which does not matter for 10 kHz), but I'd guess both will work equally well. You could choose depending on price and availability.

    Hello NCal

    To add to what Clemens said either device will work for your application.  if your are looking for an soic package device you can consider either the CD74HC4052M96 or  SN74LV4052ADR as both of these devices will have longevity and not be EOLing any time soon.

    The main difference between these devices is that  the  SN74LV4052A operates on a single supply while the CD74HC4052 can operate on both single and dual supply.

    If you are just  looking for a device to operate at 3.3v supply you can use the SN74LV4052A.

    Please let me know if you need any further assistance!

    Regards,
